Induction cooktop makes loud buzzing or humming noise at certain power levels.

Safety first: Noise alone is not usually dangerous, but ensure cookware is stable and the cooktop is properly installed.

• Try different cookware: Use heavier, flat-bottomed induction pans. Noise often decreases with better-quality cookware.
• Change power level: Slightly reduce the power setting; many induction units are quieter at slightly lower levels.
• Check mounting: With power off, remove the cooktop and verify that the induction coils and chassis screws are tight.
• Normal vs abnormal: A moderate hum is normal; sharp rattling or metallic clanging may indicate loose parts that should be tightened by a technician.
